'06 FSR 120 Expert Bike or S-Works Frame.....

I currently ride an XL Blur with all the bling bling, but the frame feels a little small for me and pedal smack is really getting on my nerves. I could get an Expert for Bike for $2800 and sell my complete Blur (swapping some components) or get an S-Works frame for $2200, swap over all my stuff from my Blur and sell the Blur frame. I know the FSR has a slightly higher BB (13 vs. 12.7) and longer TT (25.1 vs. 24.1). Question, is the Brain Fade reliable? Is it smooth over rooty trails? I like the efficiency of the Blur with almost no bob when climbing out of the saddle...how is the FSR going to feel when climbing out of the saddle with the Triad or the Brain Fade??
